This was a problem in Crysis 2 as well and seems to still not be resolved in Crysis 3.

Vegetation appears to be locked at 30fps and appears to be move in jerky movements. Crysis 1 does not have this issue and when I played Crysis 2 I chalked it up to a console "optimization" left over on the PC version.

With how much work goes into some of the graphics of this series, I don't get how they don't notice issues like this. It is only apparent if you are above 30 FPS since the vegetation will just match the rest of the game's frames. It is similar to the PC release of Halo 1 where all character animations could not be interpolated and only had 30 keyframes a second. Extremely distracting and ugly.

Any fix on this or cvar I can changed?

i7 2600K
8GB ram

Shouldn't be my rig... obviously.

Thanks!
